This invention relates to improvements in gas pressure regulators and consists of the novel combination Ol.(l8Vi(GS and the. novel features of construction hereinafter fully described and claimed. g

The object of the invention is to provide a simple and practical pressure regulator which may be used in connection with any gas meter to provide a continuous ilow. of gas ate low pressure through the meter and the service pipes in a building or the like, when the gas in l-hemain leading to the building is under high pressure.
